Super hybrid rice-from 900to 1000: not just a digital breakthrough
On October 10, Yuan Longping (front right) checked the growth of hybrid rice in the super hybrid rice "Y Liangyou 900" in Hongxing Village, Hengbanqiao Township, Xupu County, Hunan Province.
On October 10, Yuan Longping answered reporters' questions at a press conference held at Hongxing Village, Hengbanqiao Township, Xupu County, Hunan Province.
On October 10, workers harvested rice in the super hybrid rice "Y Liangyou 900" in Hongxing Village, Hengbanqiao Township, Xupu County, Hunan Province.
On October 10, workers measured the area of the super hybrid rice "Y Liangyou 900" in Hongxing Village, Hengbanqiao Township, Xupu County, Hunan Province.
On October 10, an expert group appointed by the Ministry of Agriculture tested and accepted the yield of super hybrid rice "Y Liangyou 900" in Hongxing Village, Hengbanqiao Township, Xupu County, Hunan Province. the average yield per mu was 1026.70 kg through random sampling. this marks the success of China's super hybrid rice in the fourth stage with a yield of 1000 kg per mu led by Yuan Longping, the father of hybrid rice, and also marks a new level in China's hybrid rice breeding technology. It is of positive significance to China's food security.
From the target yield per mu of 700kg per mu in 2000, 800kg per mu in 2004, 926.6 kg per mu in 2011, to 1026.70 kg per mu in 2014, hybrid rice breeding research in China has made four consecutive jumps that have attracted worldwide attention in the past 14 years.
Industry insiders believe that the future development prospect of super hybrid rice depends on two aspects, one is the effect of actual promotion. The second is the development of breeding technology. Cheng Shihua, head of the expert group and director of the China Rice Research Institute, said: "with the realization of the goal of the fourth phase, it means that China's hybrid rice breeding technology has been upgraded to another level. To be sure, the whole level of commercial breeding with enterprises as the main body will follow. In the process of popularizing hybrid rice, we also need to simplify planting techniques, establish a set of methods suitable for field cultivation, and train farmers. " The popularization and promotion of super hybrid rice will be a comprehensive project.

The risk of sudden disaster of diseases and pests in late rice requires strict prevention and control by the Ministry of Agriculture.
Since the beginning of autumn, the temperature in the middle and lower reaches of the Yangtze River, the south of the Yangtze River and most of South China is more than 1 ℃ higher than the normal year. The uncool climate in late autumn is very conducive to the occurrence and damage of the two migratory pests of rice. There is a sudden emergence of double cropping late rice in South China and Jiangnan and some single cropping late rice in the middle and lower reaches of the Yangtze River.
